活塞

Features: 1 to the Al-Si eutectic alloy composite added a variety of heat-trace elements and, through orthogonal experimental design and optimize the use of rare earth elements - Modification of phosphorus and salt air brick bottom melting technology, access to the ideal Detroit microstructure - in high intensity, good plastic α-Al matrix on the distribution of the large size of coarse crystal silicon and Chinese characters or fish-bone-shaped iron phase, raising the Pistons at room temperature plastic and high temperature strength, lower raw material costs.

通过向共晶铝硅合金中复合添加多种微量热强元素，并通过正交试验优化成分设计以及采用稀土－磷盐复合变质处理和炉底透气砖熔炼技术，获取理想的活塞金相组织——在强度高、塑性良好的α-Al基体上分布尺寸较粗大的共晶硅和汉字状或鱼骨状铁相，提高活塞室温塑性和高温强度，降低原材料成本。

Therefore, when the piston is pushed up in the cylinder, the air in the cylinder is trapped above the piston and compressed.

因此，当活塞在气缸里被推动向上时，气缸内的气体便被集聚在活塞上面并被压缩。

According to the structure and force of the piston, the piston can be simplified as axisymmetric model.

根据活塞的结构和受力，可以将活塞简化为轴对称模型来分析。

In order to determine the temperature distribution in the piston, the boundary condition of the piston must be correct.

为了模拟活塞内的温度分布，必须准确地确定活塞所处的边界条件。

The high performance brake system features 380 mm vented discs with 8 piston fixed aluminium callipers at the front and 345 mm vented discs with 4 piston fixed aluminium callipers at the rear.

高性能刹车系统的特点380毫米通风盘与8活塞固定铝卡尺于前面，而345毫米宣泄光碟与4活塞固定铝卡尺在后方。

Twin piston alloy callipers at the front and single piston callipers at the rear bring the large-diameter wheels to rest.

前轮是双活塞合金制动钳，而后轮是单活塞制动钳，可对大尺寸车轮进行制动。

The carbon-fibre discs provide brake pressure of up to 180 bars, combined with eight-piston monobloc callipers and titanium pistons fitted with fine steel heads and ceramic heat protectors.

碳纤维制动压力光盘提供高达180条，有八个结合活塞整体式活塞卡钳和钛钢精美陶瓷头和热保护装置。

The membrane isolation pumps is one kind of hydromass transportation hydraulic system,can reduce the cartage expense greatly,but indirectly brings the huge social efficiency,safe reliable,the work rate is high,may not stop nearly carries on the whole year to transport,does not have the material to lose nearly,the easy automatic control,to be advantageous for the maintenance management The hydraulic pressure diaphragm pump is one kind of fill domestic diaphragm pump which we develops in high-pressured,the small curr ent capacity pulp transportation aspect blank pumps plants,it and the common diaphragm pump main difference is:Has substituted for the crank connecting rod,the reduction gear using the hydraulic pump and so on aseries of equipments direct drive piston motion,this causes its structure is greatly the simplification,the cost drops greatly;When at the same time also requests the piston the commutation confidential assurance extremely accurately,but must realize this point theoretically and all has the very great difficulty in fact.

膜隔离泵就是一种浆体输送的液压系统，能大大降低运输费用，可间接带来巨大的社会效益，安全可靠，作业率高，几乎可不停地进行全年输送，几乎没有物料损耗，易于自动控制，便于维护管理。液压隔膜泵是我们开发的一种填补国内隔膜泵在高压、小流量矿浆输送方面空白的泵种，它与一般的主要区别是：利用液压泵取代了曲柄连杆、减速器等一系列装置直接驱动活塞运动，这使其结构大为简化，成本大大下降；但同时也要求活塞的换向时机要把握得非常准确，而要实现这一点理论上和实际上都存在很大难度。

The influence of the train-induced air on subway station and the comfort level of subway station in dynamic and transient conditions are analysized based on experimental data.

本文在大量现场实测的基础上，重点研究三方面的内容，即活塞风对地铁环境的影响规律、活塞风的有效利用对地铁通风空调系统能耗的影响和带风口屏蔽门系统在北方城市的适用性。

When Carp vehicle fuel economy stick to the running car engine cooling system of water tanks (also called the "expansion of the pot"), after the car in a moving process, the engine heat and heat transfer to the cooling liquid, heating and cooling liquid Carp Festival Oil rods in the "Bioglass" play a role and have a lot of negative ions, with a lot of negative ion engine coolant along the cylinder piston and the cylinder head outer space waterways cycle, formed around the cylinder piston engine of the electromagnetic field.

当卡普汽车节油棒投放到汽车发动机冷却系统副水箱里后，汽车在行驶过程中，发动机发热并将热量传递给冷却液，受热的冷却液与卡普节油棒中的&Bioglass&发生作用并产生大量的负离子，充满大量负离子的冷却液沿着发动机活塞缸体和缸盖外壁的水道空间循环，形成环绕发动机活塞缸的电磁场。，发动机活塞缸中的混合燃料气体在这种电磁场作用下，形成阿萨卡瓦效应，燃烧增强、爆发力增大、燃烧效率提高，从而降低汽车燃料消耗、提高发动机动力、显著减少尾气排放。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
